STATION-INDICATOR.

To all 'wlwm itmayaconcem:

. .Be it known that I, JULIUS Harms, a'

citizen of the United States of America, and

resident of Philadelphia, Pennsylvania, have 1nvented-'.certain'.- new and useful Improvements inStation-Indicators, of which the following is'a' specification.

r- This invention relates to certain new and useful improvements 1n station indicators des1gned primarily for .useupon passenger cars to indicate to the passengers the next street to be reached. or'approached by the car. .The present invention has for its objects 3.111011 others'to provide asimple and improv construction which shall be efiicicnt and reliable in its action, not liable to get out of order, in which. the parts may be readily asseinbledxor'dissembled and by which analarm will be sounded eachtime the, indica tor or're ster. is changed, so as to call attention of t e passengers to the fact in order that theyxxmay; know when their street is to be. reached.- 'I. *employ a roller upon which the cloth'or-canvas is wound,'-a-nd a flat faced rollerupon: which: the canvas or cloth. is

wound f'romx-thefirst-namedroller so that .the' inscription on the canvas will be exposed fiat and in full "view. i Novel means are employedfo'r operating the flat faced roller.

The two rollers are suitable means are em rollers at eachturn. Theroller-actuating (geared together, and p oyed for holding the means may be operated by a cord or chain, or by other convement means as may be found'most-expedlent.

, Other objects and advantages. of the inven- *tion will hereinafter appear and the novel features thereof-Fill be particularly pointed out in the ap endedclaims.

The-invention is. clearly illustrated in the accompanying.=' drawings which, with the l-numerals of refei euce marked thereon, form apartofathisspeification, and in'which Figure a face view of the improved station ind cator. Flg; 2 is a vertical longitudinal section through the same just back of the face plate ioridoor. Fig. 3 is a vertical itra'nsversesection on the line 3-3 of Fig. 2- irlooking in thedirection of the arrow. Fig. 4

are contained, said case being provided with a suitable front 2 which in this instance is shown as in the form of a door h'in d to the bottom ,4 of the case by suit-able ingest. At one end the case is provided with a com-' partm'ent 5 closed by a removable cap or. end

ranged a bell 8 and the hammers and accessoriesby which the alarm is sounded. The face or' door 2 is provided with a suitable by a transparent plate so that the name of the street may be seen therethrough. The inner face of the door 2 is providedwith a vertically curved recess 10 to permit of the and a suitable fastening device 11 may be provided for holdi its closed position but allowingof opening of the same to permit access to the interior of thg case for repairskor other purposes.

n o the she? s 13 and 14;of the upper and lower rollers, the upper one of whlch and the lower one also, if desired) is made at faced mame of the street on the cloth or canvas.

to the said rollers so as to be wound upon a collar 19 having a plurality ofradial openings 20, one for each flat face of the roller, while 21 designates a spring actuated pin actuated by the spring 22 within the .vertical lower end of this pin or rod being screwthreaded, as seen M21", and provided with a nut 25 on said threa d'ed portion. This pin automatica'lly engages into the appropriate hole 20 of thecollar 19 as the roller is turned, as will be readily understood, so as to insure pieced held in place by suitable means as the screws 7. :Within this compartment 5 is 2111- opening 9 which may be open or protected so as to better present to the observer "the.

and unwound therefrom, said cloth or canvasv On the shaft13 of the upper roller is fixed operation of the parts soon to be described,

ng the frontor door 2 in I site interior walls 12 are mounted 15 is the cloth or canvas attached at its ends casing 23 secured to the adjacent wall 12, the

, the stopping of the roller in proper position 116 to present the name of'the street squarelyand 'fiatly before the opening 9. The shaft13 is extended at one end, and removably and'ad: justably secured thereto by means of a set screw or the like, 24 is a collar 25 'rigid with which are the disks 26 parallel with each other and connected by thepins 27 there being as many pins or rods as there are flat faces to the upper roller. 1 a w 28 is aplate afiixedto the wall, 12 or to the walls 29 at the back of the rollers, and having its outer end extended at a right angle,

as seen at 30 in Fig. 3, where it. receives the screw or other pivot 31 of thetwo curved levers 32 and 33, seen best in Fig. 3, around which pivot is also coiled a spring 34, the ends 35 and 36' of which extend in opposite directions and the'end 35'engages the pin 37 on the lever 33 and the end 36 engages the pin 38 on the lever 32, as seenclearly in Fig. 3. I On each of these curved levers is pivoted,

: as at 39, a pawl or detent 40, said-pawls be-' ing oppositely disposed and normally .extending substantially vertically, as seen best in F ig.'3, and adapted when actuated, aswill soon be described, to engage the pin 27 which stands in the path thereof. Each pawlhas an arm 41 extending at substantially right anglestherefrom at a point near its pivot and adapted to engage a stop pin 42 projecting laterally from'its adjacent curved lever.

To each of the pawls -upon the side of its leverto which the pawl is pivoted. this is clearly illustrated in Fig. 3.

pivotjopposite the arm 41 is attached, or'

bears thereagainst, a'fiat spring 43, the other end of which engages a-pin 44 on. the curved All of The upper curved lever has its free end provided with'an opening 45 to which is attached one end of a cord,'chain or the like 46 which passes downward through an opening 47 in the bottom 4 of the case and around a pulley 48zsecured to the under side of said bottom-and thence over another pulley-49 on the bottom'of the'case and thence dow nward into position to be operated by the motorman, conductor or other authorized person.

Thelever 32 has in its free end'an opening 50-towhich is attached one end of a cord or the like 51 which passes upward through an opening 52 in the top. of the case and over a roller 53 secured upon the outer face'of said top 1 and thence downward through an.

opening 54 in the bottom "of the case and over suitable rollers secured to the under face of said bottom, as sh0wn, and thence downwardly to a convenient point within the'reach of the conductor, 'motorman or other authorized person. It will thus-be readily seen that each time one of the herds is pulled the curved lever to whicl it s at tached will be moved on its pivotinthe direction of the pull thereon, and the pawl 40 attached to said lever acting aga nst. its appropriate pin 27 will move the disks 26 i a- Modifications n detail may be resorted to and .consequently'the roller on the shaft 13 in the proper direction. The cord should be pulled down and 1 let fly back quickly, the

H spring 34. acting,'by appropriate arm, to

return the lever to. its normal position. ;The

spring 43'acting 'on'the pawl servesto allow it to'yield to pass the pin, when the spring returns it to its Iiormalposition ready for another operation. As the roller turns the rod or, pin 21 automatically engages in its appropriate opening 20 to hold the roller against accidental movement. The engage ment-of said .pinin the opening, however, is

only such as to prevent this movement but not sufiicient to prevent being forced backward into its casing against its spring as the shaft is rotated by the actuation of the cord and its appropriate lever etc.

In order to sound an alarm each time the roller 1s operated I provide a hell 8 secured to the wall 55 and to the free end of each of the curved levers 32 and 33 I attach cords 57 and 56. respectively, the-other ends'of which extend through openings-58in the wall 55 and over rollers 59 mounted therein, the other end ofreaclr of said cords being connected to an eye. or the like 60 of an arm 61 movablein a guide 62 on the outer face .of-the wall 55, said arm being provided intermediate its ends with an eye or, the like 63 to which is attached one end of a spring 64, which is coiled, as seen at) 65, around a suitable screw or the like 66 held'inthe wall 55 and the other end of each being suitably secured, as. at 67, to the top and bottom of.

the case, as "shown. By this nieans,1as the cord which operates thelevers is pulled, say for instance cord 51 and "the lever 32 is moved on its pivot so that its free end moves upward, the cord 57 will be pulled in the direction indicated by the arrow 54- and the spring'65 put under tension. When the op erating cord is released the spring pulls the cord '57 and consequently the arm 61 in the opposite directioinwhcn the end oreye- 60 thereof will be thrown quickly against the bell and sound an, alarm. Hence at ach partial revolution of the roller so as to.

change the-name of the street, analarm will be sounded to call the attention of the pas within the scope of the appended claims without departing from the spirit of the invention or sacrificing any of its advantages.
